The process is based on the coagulation-flocculation of colloids and the precipitation of metals in dissolution, using a suitable basic pH treatment. The formation of floccules of suitable size and density permits the subsequent sedimentation in the settling tank.
Controlling the pH range is a stage that limits the operation of physical-chemical plants in treating industrial effluents. Devices are used that guarantee the continuous functioning of the pH measurement and regulation system. By using these devices we achieve:
a- Effectiveness of precipitates.
b- A balanced chemical composition for treated water.
c- Low reagent consumption.

The whole process is automated and controlled by a microprocessor, to visualise messages and help with the maintenance of the machinery, as well as to detect possible faults.

Sludge treatment using filter presses.
Automatic or manual filter press for chambers to produce highly compacted sediment ‘cakes’. Applied for the fast filtering produced in sludge from ceramics, granite cutting, marble, terrazzo, porcelain tiles etc., and in the treatment of mineral sludge.

Biological water purification using fine bubble diffusers
Fine bubble diffusers are more highly efficient at correctly oxygenating liquid masses than any other type of aeration, with a lower energy cost.
